Notifications for battery and text

A quick question for y'all.

1) Is there a way to turn off the notification when the battery is fully charged? I'm talking about the display part. I charge in the evening and when the phone is fully charged, the screen comes on and is really bright in a dark room. It's bright enough to wake a person up from sleeping.

2) I received a text the other day and after reading it noticed a red "1" was still in folder icon on the desktop. It does not want to clear after reading the message.

1. I have never figured out how to stop the screen from awakening. The "fully charged" sound was aggravating too. I removed it after rooting. You could turn your phone face down while sleeping. I'm not sure if the "silence" feature of turning the phone over to kill sounds would affect your alarm or not.

Thanks Ollie. I turn my phone off at night. I use a "normal" alarm for the morning.
I cover the display now so as not to wake us sleeping, but I don't like the fact that my screen is just running wild and burning away for nothing.
I looked and didn't see anything in hidden menus for it like I did for the Fascinate either.
Maybe an upcoming ROM will have this as an option to turn off....

2) I was wondering about this. So far this has only happened one time, so not a huge issue yet.
